Light power on and then off..
Short circuited component at its main board. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. Pull up older posts.
Give a special attention to its horizontal output transistor. Replace it, and check. Check this device for collector to base, or collector to emitter leak. Even a slightest leak, will cause sivere problem.
